ProFlex Commander Adaptive Flex Fuel System

The Advanced Fuel Dynamics ProFlex Commander is a patented adaptive flex fuel system that enables your 1997-04 C5 Corvette (LS1/LS6, Base or Z06) to utilize E85 fuel, leading to increased power and cooler engine temperatures. This complete system provides everything needed to run E85 and is 100% dyno tested for safety and performance. Installation is designed as a simple DIY process, typically taking under an hour with standard tools. Featuring patented BlendSense™ technology, the ProFlex Commander adjusts in real time with a 30-millisecond refresh rate, allowing seamless switching between gasoline and ethanol at any time. It improves injector management, delivering more power whether on gas or E85, with documented gains of 7-10% more wheel horsepower and torque on E85. Crucially, no tuning is required; it is compatible with stock or performance gas tunes and adapts instantly to any new tunes applied. The system also contributes to cleaner emissions and lower cylinder, oil, and coolant temperatures. For those seeking higher performance, the Commander Pro option is available for vehicles with upgraded fuel systems, aftermarket forced induction, or larger fuel injectors (600cc/60 lb/hr or bigger). The Standard Commander is recommended for stock or lightly modified, naturally aspirated vehicles with factory fuel injectors. The product line also offers Standard and E-Sense fuel sensors, with the latter providing fuel temperature monitoring and unlocking real-time data in the ProFlex Connect app for modified fuel systems. This system is compatible with power adders and bolt-on modifications. The ProFlex Connect app, available for iOS and Android, provides real-time ethanol content, E85 pump locations, and system diagnostics via Bluetooth. The ProFlex Commander product line is backed by a limited 12-month warranty.
